guys please help me on my problem. my aircon is very unstable on my gt turbo starlet '96. i have to rev the engine first for the aircon to cool. i also noticed that if idle is at high 1000rpm, the doesnt turn on. there is an adjuster near the aircon soleniod im trying to adjust and it affects the rpm. i also checked the condenser pressure its just at 100. which is supposed to be at an average of 250. i already replaced evaporator, expansion valve and drier but nothing changed. do i need to replace condenser as well? if someone knows how to fix this please help me....thanks
